Patented June 21, 1932 PATENT OFFICE JERRY TYLER, F HSKEGON HEIGHTS,MICHIGAN VEGETABLE SPBAYIN G DEVICE Application led February 16, 1931.Serial No. 515,938.

This invention relates to a vegetable coolingtable or tray wherein wateris diffused through a novel sprav head and in which the stale air leavesthe table from underneath the 6, same.

One defect of tables or trays of this character hitherto manufacturedlies in the fact that the odors and foul gases tend to remain inproximity to the vebetables themselves or in some instances. theseobnoxious fumes leave the vegetables by rising therefrom.

In my improved device I overcome the aforesaid objection b v providingair circulating means below the table or tray whereby the odors from thevegetables are drawn downwardly from the table and disseminateunderneath of the table. Such a feature has two advantages. In the first.place the vegetables will maintain their quality for a so longer periodof time because the destroying odors and air are continuously ydrawnaway from the vegetables and such are replaced by sweet and clean air.In the second place the obnoxious departing fumes or odors are drawndownwardly through the table and leave the table in proximity' to thefloor thus preventing any objection to the table on account of one beingable to smell any odors from above the vegetables. This method of aircirculation forms a separate invention and is made the subject matter ofmy application for a ventilated tray. tiled February 1. 193:2. SerialNo. 590.078.

The principal feature of this invention lies in my novel nozzle or sprayhead which causes the water to be formed into a vapor or mist whichflows outwardly from the nozzle o onto the vegetables. The drops ofwater which are not diffused into a vapor are carried back underneaththe table without coming in contact with the produce carried by thewoven wire shelves of the table. `Thus all of the water which comes incontact with the produce is in the form of a very fine vapor which coolsthe air in all directions and which settles downwardly over thevegetables and finallv drains into the trough carried along theunderside of the table.

In the drawing:

Fig. 1 shows a perspective view of a cooling table embodying myinvention. A

Fig. 2 is a longitudinal cross sectional view through Fig. 1. Fig. 3 isacross sectional view taken at right angles toFig. 2.

Fig. 4 is aview through my improved spray head, parts being broken awayin order to clarify the disclosure.

Similar numerals refer to similar part-s throughout the several views.

Referring to theidrawing. especially to Fig.

1, l0 indicates the sides of my novel table and 11 the ends. these partsbeing preferably 65 formed of galvanized sheet steel and being fastenedtogether at their ends. Suitable supporting legs 12 may be fastened tothe corners of the frame structure formed by the sheet metal membersjust referred to.

The upper edges of the side members 10 are turned inwardly anddownwardly to form a U-bend as shown at 13 and the vertical portions 14of the bale plates 15 extend upi' wardly into this groove. 7

The baffle plates 15 slope inwardly and downwardly toward each other butterminate some distance apart as clearly shown in Fig.

3. A trough 16 extends lengthwise of the table. being supported uponinturned flanges 17 formed on the ends 11. and spaced downwardly fromthe terminating edges of the baille plates. Thus a considerable space ishad between the plates and the trough whereby the cool air may passdownwardly' and 85 outwardly vtherebetween as indicated by the arrows B.See Fig. 3. The trough has a drain pipe 18 leading therefrom.

Wire screens or shelves 19. preferably having a tinned finish. extendacross the table 9 and rest upon the.. baille platesv adjacent thevertical portion 1'4.

An inlet pipe 20. having a suitable control valve 21 at one end thereof.see Figs. 1 and 2. is equipped with a single riser pipe 22. as shown. Acap 23. having a needle-like orifice 24. is tapered on its outer face asindicated at 25. and is threaded onto the top of the riser pipe 22. SeeFig. 4.

A collar 26 is tapered to removably fit the we cap 23 and radial vanes27 extend therefrom to a dome or shield member 28 whereby the same issupported.

The dome or shield member 28 is interiorly threaded, as shownat 29, anda depending pipe 30, somewhat larger in diameter than the riser pipewhich it encircles, engages these threads. The dome member has an impactplate or disc 31 fixed thereto, as indicated at. 32, and windows oropenings 33 are formed therein. These windows are in the same horizontalplane as the bottom of the impact plate.

The operation of my device is readily understood. After the vegetablesand fruits are placed upon the screens 19 the valve 21 is turned onwhereby the water issues with considerable velocity against the smoothface of the impact plate 31. This causes a line mist or spray to resultand the windows in the dome allow this vapor to fioat outwardlywhereupon it gradually settles downwardly upon the produce and fruit.The larger drops of water which are not vaporized or broken up dripdownwardly within the dome and drain downwardly inside of the pipe 30into the trough 16. These drops of water Yform a'slight waste which isnot utilized.

The water vapor which settles upon the vegetables gradually permeatesdownwardly therethrough and soon cools the air both above and below thevegetables. The odors and gases which are inherent to the produce, andwhich become unpleasant as the age of the vegetables increases, arecarried downwardly by the How of water and also due to the fact thatthey are cooled. The cooler air flows downwardly between the trough andthe baille plates and below the .table where it is disseminated in anyartificial or natural manner.

Having thus revealed this invention, I claim as new and desire to securelthe following combinations and elements, or equivalents thereof, byLetters Patent of the United States:

1. ,A vaporizing unit consisting of a vertical pipe, means for supplyingwater under pressure to the pipe, a cap closing the upper end of saidpipe, said cap having a small hole therethrough, a dome surrounding thecap and extending upwardly thereover, means fastened to the cap and thedome whereby the dome is supported, said dome having several slots nearits top, an impact plate having a surface and means extending throughthe dome and adapted to support the impact plate with the said surfacein alinement with the axis of the hole through the cap.

2. A vaporizing unit comprising the elements in combination as recitedin claim'l but further characterized by the fact that the impact plateis supported in substantially the same horizontal plane as the saidslots.

of the pipe, said cap having a small opening therethrough, a dome memberenclosing the cap, said dome member having several windows therethroughand a plate depending from the dome, said plate being spaced from thesmall opening in the cap but in line therewith.

5. A spray head as set forth in claim 4 in which the plate isat rightangles to the axis of .the opening through the cap and located insubstantially the same horizontal plane as the windows.

6. In a device ofthe class described, an upwardly extending pipe, meansfor closing the upper end of said pipe, said means having a smallopening therethrough, a dome surrounding said upper end of the pipe andhaving lateral openings therein, an impact surface located within saiddome and in alinement with the opening in the pipe clo-l sure, a secondpipe of greater inner diameter than outer diameter of the lirst pipe andsurrounding said first pipe, the upper end of said second pipe being incommunication With the interior of said dome and means for supportingsaid dome.

7. In a device of the class described, an upwardly extending pipe, aclosure for the upper end of said pipe having a small openingtherethrough, a dome surrounding the upper end of said pipe and havinglateral openings therein an impact surface within said dome and inalinement with said opening in the pipe closure, a second pipe joined to-the lower end of said dome and communicating with the interior thereof,said second pipe surrounding said first pipe and having a larger innerdiameter than the outer diimpact surface and said jet, Said shielding'means including a drainage pipe surrounding the pressure pipe.

In testimony whereof I affix my signature.

JERRY TYLER.
